Ironing board permanently set up. My futility is tiny so we have a small wall-mounted ironing board that folds down against the wall and a wall-mounted iron-holder with the socket right beside.
Place for wall-mounted cordless vac to be stored (for little run around and pick up the bits cleaning jobs)
Plumbed in condenser dryer so no need to empty the water out.
Stacked washer dryer - so nice to not bend when sorting out the tumbler!
Extractor fan to leave on when washing is drying in there so doesn't get too damp and stuffy (esp. true in internal room or if in use when out of the house so windows can't be open)
Somewhere to store the laundry basket when not in use
Shelves/cupboards to keep bulk buys eg: 3 for 2 washing up liquid, large washing powder, half price dishwasher tablets
wall mounted drying rack at ceiling height
Sink with squirty hose tap for ease of filling buckets and washing poo off kids clothes
My futility is tiny (less than 2m by 2m) so we cram a lot in! Boiler and sink also in there.
